Abstract

Claims (36)

1 . A controller usable with a surgical instrument, wherein the controller comprises:

a circuit comprising an input and an output, wherein the circuit is configured to:

receive, at the input, a signal from a sensor, wherein the signal corresponds to a displacement measurement of a button of the surgical instrument; and

control, at the output, a first energy output or a second energy output as a function of the displacement measurement according to a non-linear curve, such that:

a first change in the displacement measurement results in a first disproportional change in energy output within a first range of the non-linear curve; and

a second change in the displacement measurement results in a second disproportional change in energy output within a second range of the non-linear curve;

wherein the second change is greater than the first change; and

wherein the first disproportional change is greater than the second disproportional change.

2 . The controller of claim 1 , wherein:

the circuit is further configured to compare the displacement measurement to a first threshold and a second threshold;

the first range of the non-linear curve occurs above the first threshold and below the second threshold; and

the second range occurs above the second threshold.

3 . The controller of claim 1 , wherein the circuit is further configured to:

compare the displacement measurement to a first threshold and a second threshold;

control the first energy output to apply first energy or the second energy output to apply second energy at a first level based on the displacement measurement being above the first threshold and below the second threshold; and

control the first energy output to apply first energy or the second energy output to apply second energy at a second level based on the displacement measurement being above the second threshold;

wherein the second level is greater than the first level.

4 . The controller of claim 3 , wherein the circuit is further configured to apply zero energy at the first energy output and zero energy at the second energy output based on the displacement measurement being greater than zero and below the first threshold.

5 . A controller usable with a surgical instrument, wherein the controller comprises:

a circuit comprising an input and an output, wherein the circuit is configured to:

receive, at the input, a signal from a sensor, wherein the signal corresponds to a displacement intensity measurement of a button of the surgical instrument; and

control, at the output, a first energy output or a second energy output as a function of the displacement intensity measurement according to a non-linear curve, such that:

a first change in the displacement intensity measurement results in a first disproportional change in energy output within a first range of the non-linear curve; and

a second change in the displacement intensity measurement results in a second disproportional change in energy output within a second range of the non-linear curve;

wherein the second change is greater than the first change; and

wherein the first disproportional change is greater than the second disproportional change.

6 . The controller of claim 5 , wherein:

the circuit is further configured to compare the displacement intensity measurement to a first threshold and a second threshold;

the first range of the non-linear curve occurs above the first threshold and below the second threshold; and

the second range occurs above the second threshold.

7 . The controller of claim 5 , wherein the circuit is further configured to:

compare the displacement intensity measurement to a first threshold and a second threshold;

control the first energy output to apply first energy or the second energy output to apply second energy at a first level based on the displacement intensity measurement being above the first threshold and below the second threshold; and

control the first energy output to apply first energy or the second energy output to apply second energy at a second level based on the displacement intensity measurement being above the second threshold;

wherein the second level is greater than the first level.

8 . The controller of claim 7 , wherein the circuit is further configured to apply zero energy at the first energy output and zero energy at the second energy output based on the displacement intensity measurement being greater than zero and below the first threshold.
